Police in the Ukrainian city of Odesa say 31 people have died as the result of a building fire that broke out during a clash between pro-Russia demonstrators and supporters of the central government in Kyiv.
The statement said the fire broke out in a trade union building on Friday, but did not give details on how it started. An earlier police statement put the death toll at 38; it was not clear why the figure was revised.
Police earlier said at least three people had died in a clash between the two sides.
Until now, Odesa, a key port on Ukraine's southern Black Sea coast, had largely been free of the unrest that is gripping eastern parts of Ukraine in recent weeks.
